CWE-283 (未经验证的属主) — Vulnerability Class 27

CWE-283, Unverified Ownership, is a critical security weakness where software fails to confirm that a resource belongs to the authorized entity before performing sensitive operations. Attackers typically exploit this flaw by manipulating resource identifiers or bypassing access controls to gain unauthorized privileges, leading to data breaches, privilege escalation, or system compromise. For instance, an attacker might alter a file path or database key to access another user’s private information. To mitigate this risk, developers must implement rigorous ownership verification mechanisms at every interaction point. This involves validating user permissions against the resource’s actual owner using secure, immutable identifiers rather than trusting user-supplied input. By enforcing strict access control checks and ensuring that only the rightful owner can modify or delete specific assets, organizations can effectively prevent unauthorized manipulation and maintain the integrity of their systems.
